DETAILED DESCRIPTION

Referring to FIGS. 1 and 2, an illuminating device 10 in accordance with a first embodiment of the present invention includes a light source module 11 and an electronic module 15 detachably engaged with the light source module 11.

The light source module 11 includes a printed circuit board (PCB) 111, a plurality of light emitting components mounted on the PCB 111, a heat sink 113 thermally connected with the PCB 111, and a thermal tape 114 interposed between the PCB 111 and the heat sink 113. In the present embodiment, the light emitting components are LEDs 112.

The PCB 111 is made of materials having good thermal conductivity, such as metal core printed circuit board (MCPCB) and so on. The LEDs 112 are evenly distributed on the PCB 111, and thermally and electrically connect with the PCB 111. The thermal tape 114 is used for transferring heat between the PCB 111 and the heat sink 113.

The heat sink 113 is used to dissipate heat generated from the LEDs 112. The heat sink 113 includes a heat conductive post 116 and a plurality of fins 117 radially and outwardly extending from the heat conductive post 116. The heat conductive post 116 is made of materials having good thermal conductivity, such as copper, aluminum and so on. A connecting groove 118 is defined at a bottom end of the heat conductive post 116 for engaging the light source module 11 with the electronic module 15. An electric wire 119 extends through the heat conductive post 116 and the thermal tape 114. One end of the electric wire 119 extends to the PCB 111, and the other end of the electric wire 119 extends to the connecting groove 118, for electrically interconnecting the PCB 111 with the electronic module 15.

A pair of electrical input connectors 153 and an output coupler 154 are respectively formed at a bottom end and a top end of the electronic module 15. The output coupler 154 is protruded out of the electronic module 15 to engage in the connecting groove 118 of the light source module 11. The output couple 154 mechanically connects the electronic module 15 with the heat sink 113 and electrically connects the electronic module 15 with the electric wire 119. In the present embodiment, the input connectors 153 are GU10-type connectors. Alternatively, the input connectors 153 can be other types of connectors, such as M16-type, E27-type and so on.

Referring to FIG. 3, the electronic module 15 includes a receiver 151, a control circuit 152 and a driver circuit 150. The receiver 151 is used to receives signals from a remote controller 19, and transmit the signals to the driver circuit 150 via the control circuit 152. The driver circuit 150 is used to drive the light source module 11 to operate. The input connectors 153 of the electronic module 15 are electrically connected with a selected power supply 17 for supplying power to the electronic module 15 and the light source module 11.

Referring to FIG. 3, during operation of the illuminating device 10, the power supply 17 supplies power to the electronic module 15 and the light source module 11. A command is inputted into the remote controller 19, and then the remote controller 19 sends out a wireless input signal. The receiver 151 of the electronic module 15 receives the wireless input signal, and then transmits the wireless input signal to the control circuit 152. The control circuit 152 converts the wireless input signal into a control signal and transmits the control signal to the driver circuit 150. The driver circuit 150 receives the control signal and drives the light source module 11 to operate according to the control signal, so that the illuminating device 10 can be easily controlled to turn on or turn off by the remote controller 19. Thus, a remote control of the illuminating device 10 is obtained.

Referring to FIG. 4, the remote controller 19 for the illuminating device 10 is shown. The remote controller 19 includes a display section 191 and a keyboard section 192. A plurality of keys, such as number keys, cancel key, ENTER key, ON/OFF keys, are located in the keyboard section 192. The remote controller 19 can input an operating time of the illuminating device 10 via the number keys in the keyboard section 192. The input time is displayed on the display section 191 so as to ensure whether the input time is correct. If the input time is incorrect, it can be cancelled by the cancel key C in the keyboard section 192. If the input time is correct, it can be confirmed by the ENTER key in the keyboard section 192. In addition, the illuminating device 10 can be controlled to turn on by the ON key, or to turn off by the OFF key in the keyboard section 192. Therefore, commands can be inputted into the remote controller 19 by the plurality of keys in the keyboard section 192, and the wireless input signal is accordingly sent from the remote controller 19 to the illuminating device 10.

In the present illuminating device 10, the receiver 151, the control circuit 152 and the driver circuit 150 are provided in the electronic module 15 to enable that the illuminating device 10 can be controlled by the remote controller 19. The illuminating device 10 can be easily controlled to turn on or turn off by the remote controller 19. Thus, the remote control of the illuminating device 10 is obtained. In addition, the wireless input signal can be inputted simply via pressing the keys in the keyboard section 192, which simplifies the operation of the illuminating device 10. Furthermore, the electronic module 15 is detachably engaged with the light source module 11. The electronic module 15 and the light source module 11 can easily be replaced, or repaired.

Referring to FIGS. 5 and 7, an illuminating device 20 in accordance with a second embodiment of the present invention is shown. In this embodiment, the electronic module 15 includes a driving module 23 and a receiver module 24 detachably engaged with the driving module 23. The driver circuit 250 is built in the driving module 23, and the receiver 251 and the control circuit 252 are built in the receiver module 24.

The driving module 23 defines a fixing groove 234 at one end thereof, and forms a driving coupler 238 at the other end thereof. The driving coupler 238 is protruded out from the driving module 23 to engage in the connecting groove 118 of the light source module 11, so as to mechanically connect with the heat sink 113 and electrically connect with the electric wire 119.

The receiver module 24 forms a pair of electrical input connectors 243 and an output coupler 244 at two opposite ends thereof. The output coupler 244 is protruded out from the senor module 24 to engage in the fixing groove 234 of the driving module 23, so as to mechanically and electrically connect with the driving module 23. The input connectors 243 are electrically connected with the power supply 17 which supplies power to the driving module 23, the receiver module 24 and the light source module 11. A working principle of the illuminating device 20 is substantially the same as that of the illuminating device 10 in the first embodiment.

In the present illuminating device 20, the receiver module 24 is detachably engaged with the driving module 23. Therefore, the receiver module 24 and the driving module 23 can easily be replaced, or repaired.

It is believed that the present invention and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
